IMPROVEMENT IN ANCHOR-TRIPPERS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all persons to 'whom these presents may come:

Be it known that .LJ'AMEs B. HOPKINS, of Dennis Port, of the county of'Barnstable, and State of Massachusetts, have invented a new and usefulImprovement in Anchor-'lrippers; and do hereby declare the same to befully described in the following specication, and represented in theaccompanying drawings, of which- Figure l is a top View, and

Figure 2, a side view of an anchor-tripper, as provided with myinvention, land applied to the hull of a vessel, the same exhibiting theanchor, as supported by the tripper, and4 the cable ruiming through thecathead. IIt is wellknown to mariners that the'process of casting thetluke ofa heavy anchor oi the lmlwark-rail oi' a vessel, preparatory tocoming to anchor, or dropping the anchor into the water, is often one ofmuch diiiiculty, and attended with considerable expenditure oi' time,the delay in accomplishing the matter being sometimes attended withserious consequences, if not the loss of the vessel. With theanchor-tripper, the discharge of an anchor-duke from' the rail orbulwark is a matter of easy accomplishment, requiring scarcely more thana few seconds, particularly with my improvement. v r

1am aware of the anchor-trippers described in the United Stat-espatents, No. 26,765 and 51,305, which, like mine, contain a rotarytripper and a holder thereof. Gonsequentl y, I make no claim to eitherof such patented inventions, my improvement having reference to themechanism for holding and discharging the tripper, and especially to thearrangement of such mech- `anism with respect to the rail, or part onwhich the tripper rests.

My trippcr consists of a plate, A, provided with a flange, or lip, a,and two journals, b b. The flange is and close to the lip, and are4supported on staples, or bearings c c, extended -from the rail d of thebulwark B of thexhull-C.

A slot, e, made through the plate A, receives a catchhook, f, arrangedin the rail, or bulwark, in manner as shown in iig. 1, and also in fig.4, which is a vertical section of the hook, the rail, and the plate A.

A stop-lever, g, turning on a fulcrum, h,'and formed as represented, isarranged on the plate A, and when thesaid plate is caught down bythecatch-hook, the stop-lever, on being moved up to the hook, will keepsuch hook in engagement with the-plate.

The hook serves to hold the plate down upon the rail when the fluke ofthe anchor D is hooked upon the lip a.

By drawing the stop-lever away from the catch-hook, and pressing thesaid hook back and off the 4plate A, the anchor will turn the plate andbe discharged from its lip. j

By my arrangement, the detaining-mechanism of the tripper is all withinthe rail, or bulwarlr, and on top of the said tripper, and does notextend down along and project from the inner side of the bulwark. Whenit does so, or is formed and arranged :as shown in patent, No. 51,305,it is much in the way of seamen, and liable to be accidentally trippedby ropes or by a. person, in which case it is liable to do injury to theindividual.

What I claim, therefore, as my improvement, is-- My arrangement of thecatch-hook and its stop, with the tripper A and the bulwark, or rail ofthe vessel, the stop, under such arrangement, being in and movable withthe tripper, and the catch-hook being arranged in a mortise in the rail,orV bulwark, the whole being substantially'in manner, and so as tooperate as set forth. p
